(Agaricales, Basidiomycota), a new puffball species from Jamari National Forest, Brazilian Amazon.

abstract
Despite being under intense deforestation pressure, few studies regarding the Brazilian Amazon have focused on the diversity of puffball fungi, which makes taxonomic studies in this region particularly relevant. Thus, the present work aimed to describe a new species of Lycoperdon found in Jamari National Forest, Rondônia, Brazil. Macro- and micromorphological features of the basidiomata were analysed, and the species was proposed based on comparative analyses with related taxa. Lycoperdon jamariense sp. nov. is characterised by subglobose to depressed globose basidiomata, an exoperidium covered with small spines which partially fall off at maturity, a compact cellular subgleba, a conspicuous diaphragm, and a paracapillitium covered with glebal membranes. The combination of a distinct diaphragm, characteristic of subgenus Vascellum, and a paracapillitium with glebal membranes, typical of subgenus Morganella, has not been reported in any other species of Lycoperdon, making this taxon morphologically unique. This is the second record of a Lycoperdon species from the State of Rondônia and adds to the limited knowledge of gasteroid fungi in the Brazilian Amazon.
